1. the uniformity of the distribution is not easy to control, the thickness of the desulfurizer/denitration agent material layer is not easy to control in the charging process at the upper part, the thickness of the material layer is different, and the resistance is different, so that the drift is caused, part of the desulfurizer fails in advance, and the index discharge can not meet the requirement.
2. When unloading, the desulfurizer/denitrifier falls by self gravity, but because of factors such as resistance and friction coefficient of the porous plate, even unloading can not be accurately achieved in the unloading process (namely, the bottommost layer material is unloaded according to even thickness), the unloading thickness is different, and partial medicament is unloaded when not being completely used.
3. The desulfurizer/denitrifier is totally accumulated together, pulverization is aggravated due to factors such as gravity and extrusion, resistance is increased, and system operation is greatly and negatively influenced.
4. When desulfurization and denitrification treatment needs to be carried out simultaneously, a desulfurizer/denitrifier needs to be placed in the fixed bed simultaneously, because the contents of sulfides and nitrogen oxides in flue gas are different, the service life of the desulfurizer/denitrifier is different, and when any one of the desulfurizers and the denitrifier fails to be replaced, the other material can only be replaced simultaneously, so that material waste is caused.
